Even if you walk exactly the same route each time - as with a sonnet - the events along the route cannot be imagined to be the same from day to day, as the poet's health, sight, his anticipations, moods, fears, thoughts cannot be the same.
God has wisely kept us in the dark concerning future events and reserved for himself the knowledge of them, that he may train us up in a dependence upon himself and a continued readiness for every event.
... for those of us who lived through these events, the only marker we'll ever need is the tick of a clock at the 46th minute of the eighth hour of the 11th day.
